Ammunition for Swedish M1887 revolver

[boltaction]

Does anyone know who might carry ammunition or loading equipment for the old Swedish M1887 "Nagant" revolvers, which were chambered in 7.5mm. It is supposed to be interchangeable with the ammo used by the Swiss 1882 Ordnance revolvers.

Thx

Ed

These things shot a 104-grain bullet at a tad over 700 ft/sc.

You can cast a 93-grain .32 S&W slug or a 111-grain Carbine slug and use either. Best to expand the slug to .316" first. Or start with a cast .323 for the StG-44 and size it down.

Likely friend JETHUNTER will have the right bullets, so PM him or check his listing. Good bullets.

Brass can be made from .32-20 trimmed to .900".

RCBS makes dies. Not sure if LEE does also, but it is possible.

TWO grains of Bullseye should get the bullet downrange just about as fast as factory stuff.

Hope this helps.

Smellie not to try to correct you or anything, but I have done quite a bit of playing around with the 1887 as I have a antique one made by Husqvarna in the first year , so 1897 , some of these will have a .307 or .308 bore so good idea to slug your bore , I also feel that the best is 30 carbine dies and full length 32-20 with a wadcutter. So far have only shot BP in mine. Here is a link to gunboards forum with some info. Cheers

Thank you, Jack!

This is one critter that I don't have, so I was going "by the book" because no-one had replied.

LOT easier to get moulds for the smaller slug, anyway; Lee makes 93 and 100-grainers.

What kind of accuracy do you get?

Great link, thanks Jack!

104g lead bullet at 700ft/sec may be eniemic by todays man stopper standards, but it would still, at close range, ruin someones day, would it not?

Oh yes, I have no doubts about that. Even take the little .32RF's for example, an 80gr at around 600fps and they will go through a few inches of wood with ease, that does not sound like a good time either.

We are accustom to high velocities in this day and age but the oldies still seem to have got the job done.

Anyways, this is an interesting thread. Always enjoy reading about how to feed these guys.

Yes its interchangeable with swiss. But you need to slug the barrel to be sure in bullet diameter.
i use .312 bullet in trimmed 32-20 case first sized in 8 mm lebel dies then top sized by 32 s&w die. i put 2.5 gr of trailboss/
you can find occasional ammo at shows for $4 a piece.
if you need help with it i can make some brass for you since i am set up. all you will need to reload is .32 s&w die set to seat the bullet. Pm me

Does anyone know the calculation for terminal energy, for this round or the original issued round, at (for example) 30 ft.? I am going to guess it would be in the same league as the 1882 Swiss revolver ctg.
Can we speculate on the effect on small-medium game with solid RN lead bullets in these ctgs? All hunters know shot placement is critical but can we speculate that these rounds would reliably terminate a couger size critter?

Can anyone compare the 7.5mm rounds energy, mathmatically, to the 1892 French 8mm Ordinance revolver?

All three revolvers are very well made guns, in production at around the same time.

 

[drslav]

No math here but Will be less than french service... same as Swiss. And about or slightly more than .32 S&W long. Regardless if that information this calculation is useless as Hunting with pistol at least in Ontario is not legal otherwise would be fun on rabbit. I am not aware of a rifle in this calibre. FYI.

Calculation for energy (terminal or otherwise, always kinetic) is simple but it looks hard. ONE minute with a $6 brain (mine came from Radio Shack) is all it takes.

1. Know your velocity: with a .303 it is 2440 ft/sec

2. SQUARE that figure (multiply it times itself): 5,953,600 (which looks outrageous)

3. DIVIDE the result by 450240. You get another outrageous figure, in this case something like 13 and a whole bunch of decimals.

4. Now MULTIPLY by the weight of the Bullet (for a .303 Mrk VII Ball it is 174 grains). For a .303 this comes out at almost exactly 2300 ft/lbs ME.

And that is precisely the figure you are looking for.

TERMINAL energy is calculated exactly the same way, just using terminal velocity: V squared divided by 450240, times the mass of the bullet in GRAINS.

The 450240 figure is derived from 2x the constant of Gravity, times 7000 (there are 7000 grains in a Pound). It's pure Newton.

My 1911 Steyr puts a 115-grain slug downrange at a tad over 1300 ft/sec. That is an exercise for you to play with.

It is also scary.

The old ones are fun to play with but none of them were toys.

Do have fun!
